Also, if you want to know, the sectoids are, as any xcom player knows, the 'Grays' that people claim to be abducted by, and are highly psionic.
Sloop, if your a psi-ops person, I'd suggest choosing a sectoid

Name: Razgriz
Gender: M
Race: Humans
Armor: Its a specialized Advanced Infantry Armor(AIA) that boosts the strength of the soldier by 4 times, using extremely powerful servomoters. considering a normal soldier can carry around 40 pounds of gear and still be effective, and carry 70 pounds at max, anyone wearing this armor can carry 160 pounds and still be effective, and can carry 280 pounds at most. The wearer can use any weapon they want, regardless of weight. even better, the person doesn't even have to leave the armor to releave themselves. they can shit and piss in the armor and the armor will take car of it for them. also, the armor has 5 inches of pure titanium armor, and a very reflective coating for deflecting energy weapons.
Type: Good at all, but Specializes in Advanced Rifleman/Infantry
Weapon: Primary: Advanced Ice Crystalline Assault Rifle(AICAR) with 4x high contrast sight and underbarrel HEHV grenade launcher. Secondary: Dual 12.7mm submachine pistols. Other: 10 Frag grenades, 5 Cans of HE C8 explosive, 10 Flash grenades, 5 Smoke grenades, and enough ammo for each weapon for 20 days(30 energy cells and 10 pistol mags)
Recruitment: Went to the commandos university, and enlisted as an officer. am now a captain after 3 years of service.

i already pointed out the fact that the servomotors can support that much weight. if there was no armor, the soldier could support 500 pounds. its all factored in people. think about SPARTAN armor(sorry). it weighs half a ton(1000 pounds). power armor weighs about 500 pounds.
